Silicon Control Static Transfer Switch 110VAC 50HZ 60HZ

NASN STS(Static Transfer Switch), is designed to transfer critical loads between two independent AC power sources without interruption or with a transfer time of less than a cycle (4ms).

The STS consists of Silicon controlled rectifiers (SCR’s), control & sensing circuits to monitor the incoming sources and transfer the critical loads connected to the secondary source when the primary source fails.

According to input AC 220Vac or 110Vac,there are 2 series. Frequency 50HZ or 60HZ can be set on LCD screen.

STS can be used for any critical applications not limited to

• Data centre

• Intensive care units in Hospitals

• Operation Theatres in Hospital

• Signalling & communications for Metro Rails, railways

• Critical IT operations

• E-commerce businesses

• Telecommunication centres
